MACHINE FOR TREATING FABRICS WITH LIQUID.

Application filed August 22, 1928'. :Serial No. 301,319.

This invention relates to machines for treating textile materials, as fabrics, with liquids of the class, for example, in which the material in endless form is extended over an elliptical reel rotating on a horizontal axis over a liquid-containing vat and the reel is rotated so as to draw from and return itto the liquid and, due to its elliptical form, in the returning operation sway or shift the fabric back and forth whereby to produce pleats or folds, which will form in a pile if, as usual, the vat is I provided with an upright somewhat inclined wall to serve as a lateral support.

goods or the like are handled and where the material is in wet condition, the reel causes,

peripheral speed when the greater diameter 1 thereof than when its lesser diameter appreaches the goods in each revolution, so that slippage of the goods on the reel ntermittently resultsi This invention consists in combining, with such a reel m an apparatus of this class,-

means to drive the reel at alternately accelerated and retarded speeds timed so that the maximum and minimum speeds shall'respectively occur when the minor and major reel diameters approach the material in the rotation thereof'in the normal or working direction.

In the drawing, 7

Fig. 1 is a side elevation, partly broken away, of a machine embodying the invention and showing one form of driving means; I

Fig. 2' is a side elevation of another form of driving means, partly broken away; and

Fig. 3 is a right side elevation of certain )arts a 3 nearin in Fi 2.

In the drawing, 1 is a dye vat having one end wall l thereof sloped upw'ardly'and outwardly so as to form the hereinbefore mentioned lateral support against which the pile of pleats is adapted to rest.

The vat has a frame 2 upstanding there from in which is journaled on a horizontal the material In mav chines embodying such reels, where fine silk form of the reel the fabric or other material 7 5, shown in endless form, will in being caused to travel endlessly by the reel when rotating also be formed in pleats 5 which form in a pile, resting against said support 1. The reel is usually driven at constant speedwherefore there is an alternately fast and slow speed ofits periphery with respect to any given radius, or fast when the reel is in the position (Fig. l) where the greater diameter is approaching the fabric and slow where the lesserdiameter approaches the fabric. 7 I r Instead of driving the reel in this manner I combine with it means to drive it at alter,- nately accelerated and retarded speeds timed so that the maximum and minimum speeds shall respectively occur when the minor and major diameters of the reel approach the material in the rotation of the reel in the normal or-working direction. Two formsof such means are herewith shown.

' In Fig. 1 the shaft 3 has ailixed thereto an elliptical sprocket 6 whose major diameter coincides with that of the reel, andona.

counter-shaft? journaled in the frame 2 parallel with shaft 3 is another elliptical sprocket 8 whose major diameter is at right angles tothat of the first diameter, the two sprockets being of the samediameters and geared together by an endless sprocket chain 9 which of course retains thetwo sprockets in the relation stated. For rotating shaft 7 and, through the described means, the reel, a worm gear 10 may be fixed to shaft 7 and have engaged with it the worm of a' worm shaft 11 driven bya motor 12. v a

In Figs. 2- and 3 the gear 13 fixed to the reel shaft 3 is circular and the driving means here comprises a circular gear 14 in mesh with gear 13 and having a radial slot 15, and a worm' gear 16 having an eccentric stud 17 engaged in said slot, 18 being the worm shaft whose worm meshes with the worm gear 16 and which drives said worm and consequently the reel.

Having thus fullydescribed my invention, what I claim is A machine for treating fabrics with liquid comprising supporting means, areel journaled therein on a substantially horizontal axis and having an elliptical periphery over which the wet material passes and by which it is adapted to be advanced, and means to drive the reel at alternately accelerated and retarded speeds timed so that the maximum and minimum speeds shall respectively occur when the minor and major reel diameters 10 approach the material in the rotation of the reel.
